c# - What is the best way to convert Action<T> to Func<T,Tres>?

Question

I have two functions in my class with this signatures,

public static TResult Execute<TResult>(Func<T, TResult> remoteCall);
public static void Execute(Action<T> remoteCall)

How can I pass the same delegate in the second method to the first one? Creating method with Delegate argument is not a way, because I am losing some exception information.

Answer 1

Wrap it in a delegate of type Func<T, TResult> with a dummy return value, e.g.

public static void Execute(Action<T> remoteCall)
{
    Execute(t => { remoteCall(t); return true; });
}
